|
muscariform |
= broom-shaped, penicillate |
solid shape |
|
Having a proximal axis that bears a distal cluster of elongate slender branches or appendages, these variously ascending to erect; like a broom. |

architecture |
|
Having two opposite broad surfaces that differ distinctly in appearance. |
|
mushroom-shaped |

Having a cylindric base and a considerably broader, pulvinate distal portion; like the generalized form of a mushroom. |
|
catadromous |
|
venation |
|
Having the first lateral vein in each pinna or primary segment of the frond arise from its midvein on the side toward the base of the frond, the pinnule or secondary segment that it leads to often disproportionately larger than the next distal ones. |

|
pith |
|
STRUCTURE |
|
The central ground tissue of a stem or, when present, of a root, consisting of thin-walled parenchyma cells; distinct and more or less soft and spongy relative to the other tissues of the axis; sometimes partly or wholly degenerating after secondary growth has begun. |
|
decurved |
|
orientation |
|
Curving abaxially. See also incurved. |
|

|
sack-shaped |
= bag-shaped, pouch-shaped, saccate |
